EUGEN HENTSCH, OF FRAUENFELD, SWITZERLAND.

EYE PROTECTOR.

Application filed February 27, 1926, Serial No. 91,057, and in Switzerland March 14, 1925.

This invention relates to eye protectors for example for automobilists.

The objects of my invention are to enable the eye protector to be brought at will into and out of use in a minimum amount of time and to avoid the possibility of mislaying or losing the eye protector and as hitherto frequently occurred to avoid breakage of the eye protector by articles thrown onto it.

I attain these objects by the means illustrated in the accompanying drawing and hereinafter described and claimed.

In the drawing Figure 1 is a front elevation of an eye protector for automobilists.

Figure 2 is a plan view, and

Figure 3 a side elevation thereof.

Figure 41 is a side elevation and serves to illustrate a modification in constructional detail.

The eye protector illustrated in the drawing has a frame formed of spring wires 1 and 2, the ends of which are connected to form spring forks 3 and 4 respectively.

The frame can be formed in one piece, as shown in Figure 1, or it may be built up of two pieces secured together. Likewise one pane of glass, muscovite or the like, or two panes can be used. The forks 3 and 4 are guided in sheaths 5 and 6 which are closed at one end and are rotatably and fixably arranged on plates 7 and Sin a similar manner to the sheaths of the jointed parts of a folding rule. The plates 7 and 8 are attachable to the head covering (not shown) of the automobilist and for the purpose of enabling the sheaths to turn on them and be yieldingly held against turning, the plates 7 and 8 have bulges 9 and 10 respectively adapted to engage depressions 11 and 12 respectively in the sheaths 5 and 6. The plates 7 and '8 are furthermore provided with pivot pins 13 and 14 respectively which connect them to the sheaths 5 and 6 respectively, and also have holes 15, 16, Figure 3, to enable them to be attached to the said head covering. In order to prevent the forks from accidentally sliding out of the sheaths, the ends of the fork prongs are bent slightly outwards and in their outermost end position are adapted to engage in holes 17, 18, Figure 3, provided in the ends of the sheaths 5 and 6 which face the frame 1, 2.

In the modification of frame shown in Figure 4: the length of the frame is reduced to a minimum. For this purpose the frame is arranged as a slide with tongue, the tongue 19 being arranged to slide in the guides 3, 4. A ring 20 is placed over the guides 3, 4' and is provided with a stop pin 21 by means of which relative movement between the guides and the tongue is limited.

The eye protector is employed by sewing the plates with sheaths to the head covering and pushing'the forks into the sheaths. If

it is not desired to use the eye protector, the part in front of the eyes is drawn away from the face until the bent ends of the prongs of the forks 3 and 4 engage in the holes 7 and 8 and is then turned over upwardly and laid on the head covering.

It will be appreciated that the part. protecting the eyes can be very quickly moved into and out of operative position and that the said part cannot easily become mislaid or lost or be laid down, as often occurs, in places where it can be broken by articles thrown onto it.

I claim An eye protector for attachment to a head covering, comprising in combination, a goggle frame, temple members extending from said frame in extended U-sha'pe and Fifi of spring character, and the extremities of each U-member bent outwardly, a guide member for each temple member designed for attachment to the head covering and each comprising a supporting plate, and a sheath presenting lateral apertures near the inner ends of its narrow longitudinal walls for cooperation with the outwardly bent extremities ofsaid U-springs in the outermost position of the U-members relative to the sheaths, the shanks of said U-spring members slidably guided in said sheaths, and each sheath mounted on its supporting plate for swin ing movement in a plane parallel to that of supporting plate, and snap-spring means for relatively locking the sheaths and their supporting plates in the operative position of the goggle frame.

Intestimony whereof he aflixes his signa ture.

EUGEN HENTSCH.
